My reason to buy this clock was the Stamp function. So you can date and time clock-exactly hold a button. For example, when you come to the office and when you leave the workplace again. With this function, I know very few watches. What you should think about when buying is that you have to find someone who cuts a bracelet. Costs a few euros extra. I dared myself. But is not for the craft lay. The clock replaced a similar Casio clock. The bracelet was there that I canceled irreparably. I assume that this clock has this design flaw here too. Again, the bracelet will cancel the housing sooner or later. My hope is simply that it is rather long over. And one more tip: The clock does not synchronize the radio signal (the time) when it is in the Stamp, TAL or Stopwatch Mode. So bring the evening best display on normal position, so that the "atomic time" is set correctly at night. Otherwise the clock keeps its promises. I am happy.
